“…Thus, seed protein electrophoretic (Cherry et al, 1970(Cherry et al, , 1972, flavonoid (Parks et al, 1975), and isozyme (Saha and Zipf, 1998) surveys were consistent with or directly corroborated the earlier inferences based on genetic and cytogenetic studies. In the last several years, these studies of phenetics, or similarity, have been supplemented by formal phylogenetic analyses, using explicit methods of genealogical reconstruction.…”

The cotton genus (Gossypium ) includes approximately 50 species distributed in arid to semi-arid regions of the tropic and subtropics. Included are four species that have independently been domesticated for their fiber, two each in Africa-Asia and the Americas. Gossypium species exhibit extraordinary morphological variation, ranging from herbaceous perennials to small trees with a diverse array of reproductive and vegetative characteristics. A parallel level of cytogenetic and genomic diversity has arisen during the global radiation of the genus, leading to the evolution of eight groups of diploid (n ¼ 13) species (genome groups A-G, and K). The evolutionary history of the genus included multiple episodes of trans-oceanic dispersal, invasion of new ecological niches, and a surprisingly high frequency of natural interspecific hybridization among lineages that are presently both geographically isolated and intersterile. Recent investigations have clarified many aspects of this history, including relationships within and among the eight genome groups, the domestication history of each of the four cultivated species, and the origin of the allopolyploid cottons. Data implicate an origin for Gossypium 5-15 million years ago (mya) and a rapid early diversification of the major genome groups. Allopolyploid cottons appear to have arisen within the last million years, as a consequence of trans-oceanic dispersal of an A-genome taxon to the New World followed by hybridization with an indigenous D-genome diploid. Subsequent to formation, allopolyploids radiated into three modern lineages, including those containing the commercially important species G. hirsutum and G. barbadense. Genome doubling has led to an array of molecular genetic interactions, including inter-locus concerted evolution, differential rates of genomic evolution, inter-genomic genetic transfer, and probable alterations in gene expression. The myriad underlying mechanisms are also suggested to have contributed to both ecological success and agronomic potential.

“…JOHNSON & THEIN (1970) found the protein patterns of 25 species of Gossypium to be largely consistent with the conventional classification of diploids into six genomic groups. CHERRY et al (1970) also found isozyme analysis to corroborate the earlier cytological separation of genomes in Gos~vpium with minor deviations. They further found intergenomic isozyme differences to exceed differences among species or varieties within a genomic group.…”

INDEX WORDSEsterase, acid phosphatase, peroxidase, banding pattern, tissue specificity, species relationships. SUMMARYStarch-gel electrophoresis was used to study esterase, acid phosphatase, and peroxidase isozyme patterns in the primary leaves, stems, and roots of 13 species within the genus Phaseolus (P. acutifolius, P. adenanthus, P. angularis, P. atropurpureus, P. aureus, P. bracteatus, P. calcaratus, P. lathyroides, P. mungo, P. ricciardianus, domestic P. vulgaris, and wild P. coccineus and P. vulgaris). Most species showed unique banding patterns in each isozyme system. However, a close similarity in banding patterns was observed for the domestic P. vulgaris, wild P. vulgaris, and wild P. coccinkus indicating close genetic relationships, possibly through species introgression or common descent.Great differences in isozyme patterns were found for different tissues from the same species in all systems indicating the high tissue specificity of isozymes. Upon compilation of bands from all the species, a very large number of isozymes were obtained in each system or tissue, making the electrophoretic isozyme technique of high potential in studies of isozyme variants in this genus.

“…Another A-genome primary cultivar G. arboreum L. (2n ¼ 2x ¼ 26) was established in southern Asia and a third D-genome diploid species G. raimondii migrated to the western hemisphere or the New World 1-2 million years ago (Brubaker et al 1999). The 52 chromosome species including G. hirsutum and G. barbadense are classic natural allotetraploids that evolved in the New World owing to a critical interspecific hybridization that occurred during the migration of diploid species between the A-genome-like African ancestral G. herbaceum (A1) and the D-genome-like American ancestral G. raimondii (D5) (Wendel and Cronn 2002), a fact recognized in earlier cytogenetic (Phillips 1963) and seed electrophoretic (Cherry et al 1970) studies. The first of the polyploid hybrids retained the ability of fiber production that was more vigorous than the parental diploid species and subsequent polyploidization gave rise to five extant allotetraploid species, …”
